Ma ke kahua o nā ʻōnaehana hoʻokele pākaukau (BMS), ʻo kekahi o nā pōʻino i nānā ʻole ʻia e alakaʻi-acid a me Ni-Cd ʻo ka ripple current a me ka ripple voltage. ʻOiai ʻaʻole i ʻike pinepine ʻia, hana kēia mau pilikia uila e like me nā mea pepehi kanaka, e hōʻemi ana i ke ola o ka pākaukau a hoʻoweliweli i ka hilinaʻi o nā ʻōnaehana mana hoʻihoʻi koʻikoʻi i nā kikowaena data, substations, a me nā pūnaewele telecom.
ʻO ke kaʻina hana hoʻouka a me ka hoʻokuʻu ʻana o ka pākaukau he mana DC maʻalahi. Eia naʻe, ma muli o ka hoʻololi pinepine ʻana i nā loina a me nā ʻōnaehana UPS, ʻike ʻia nā ʻāpana AC makemake ʻole:
Ripple Current - Hoʻopili ʻia ka ʻāpana AC ma luna o ka DC o kēia manawa, e loli ana me ka hoʻouka a me ka hoʻoiho / hoʻokuʻu ʻana.
Ripple Voltage - Hoʻololi ʻia ka AC ma luna o ka volta DC, ana ʻia i nā helu peak-to-peak a i ʻole RMS.
ʻO kēia mau ripples maʻamau i ka 50Hz - 1kHz ākea a, ʻoiai ʻaʻole ʻike ʻia, aia nō i kēlā me kēia pōʻaiapili.
No kēlā me kēia ʻōnaehana nānā ʻana i ka pākaukau, ʻo ka nānā ʻole ʻana i ka ripple he mea pōʻino. I ka wā lōʻihi, hoʻopilikia ka ripple i ka pōʻino hiki ʻole:
Hoʻopili ʻia ka Plate Corrosion - Ke alakaʻi nei ʻo Ripple i ka hoʻokahe ʻana i nā mea hana, e hōʻemi ana i ke ola lawelawe.
Wela Nui - Hoʻonui ka Ripple i ke kū'ē a me ka hana wela; ʻO kēlā me kēia piʻi 10°C e pāpālua i nā hopena kemika, e wikiwiki ana i ka evaporation electrolyte.
Ka Pohō Kahiki - Hoʻemi ka hoʻolaha ripple lōʻihi i ka mana kūpono e 30-50%, e hōʻemi ana i ka nānā ʻana i ke olakino pākaukau a me ka hilinaʻi o ka ʻōnaehana.
No ke aha ʻaʻole lawa nā ʻōnaehana BMS Battery maʻamau?
ʻO ka hapa nui o nā haʻina BMS pākaukau e ana wale i nā ʻāpana static e like me ka volta a me ke au, me ka haʻalele ʻana i nā hopena ripple. Ua like kēia me ka nānā ʻana i ka wela o ke kino akā ka nānā ʻole ʻana i ka neʻe ʻana o ke koko - nalo nā hōʻailona olakino koʻikoʻi.
ia ʻO ke kumu e pono ai nā ʻōnaehana kiaʻi pākaukau holomua e hoʻokomo i ka nānā ʻana i nā ripple i hoʻolaʻa ʻia e hōʻoia i ka hilinaʻi maoli.
Ma ke ʻano he mea hāʻawi honua i nā ʻōnaehana hoʻokele pākaukau, hāʻawi ʻo DFUN i ka PBMS9000 Series, i hoʻolālā ʻia no nā kikowaena data nui, substations, a me nā ʻōnaehana koʻikoʻi. ʻOi aku ia ma mua o ka nānā kuʻuna me ka ʻike ripple kiʻekiʻe:
1. Ana Kiekie-Precision
Ripple kēia manawa: 0~400A peak, 50Hz - 1kHz, hoʻonā 0.01A
ʻO ka Ripple Voltage: 2~100VDC peak, hoʻonā 0.01V
Hoʻopili ʻia ka nānā ʻana o ka volta, ke kū'ē, SOC, SOH, a me ka mahana
2. 24/7 Nānā Ola Ola
Ka nānā 'ana ma ka pūnaewele me ka mālama 'ikepili 5 makahiki
ʻO nā ʻōleʻa hoʻāla he nui ma o SMS, leka uila, a me ka polokalamu kelepona, pane <10s
3. Pūnaehana BMS hiki ke ho'onui a pa'a
Kākoʻo ʻia a hiki i 6 mau kaula pila (420 – 480 cell) no nā ʻeke VRLA a me Ni-Cd
ʻO ka hoʻolālā anti-interference e hōʻoia i ka hana hilinaʻi ma nā wahi UPS
Kākoʻo ʻo Modbus, SNMP, MQTT, a me IEC61850 protocols no ka hoʻohui pono ʻole.
4. Hiki ke hilinaʻi, hoʻoponopono hōʻoia
Kūlike me nā palapala hōʻoia CE, FCC, RoHS, UL
ʻO ka hoʻolālā mana pālua ʻaʻole e pani ʻia ka nānā ʻana
Ma nā papahana kiʻekiʻe me nā kikowaena ʻikepili Google a me nā ʻoihana kikowaena ʻikepili ʻelima ʻē aʻe, ua hōʻoia ka moʻo PBMS9000 i kona waiwai.
I loko o kahi kikowaena ʻikepili honua, ʻike ʻo PBMS9000 i nā mea ʻino ʻole o ka ripple 6 mau mahina ma mua, e pale ana i kahi outage UPS nui.
Hoʻonui ʻia ke ola pākaukau e 40%, e hōʻemi nui ana i nā kumukūʻai pani.
ʻO nā pila ka lālani pale hope loa i loko o nā ʻōnaehana hoʻokele pākaukau, a ʻo ka ripple kahi mea huna akā koʻikoʻi. Hāʻawi ka DFUN PBMS9000 Series i nā mana o ka ʻōnaehana kiaʻi pākaukau o ka hanauna e hiki mai ana, e hāʻawi ana i ka ʻike ripple manawa maoli a me ka nānā ʻana i ke olakino pākaukau holomua.
ʻO DFUN PBMS9000 — he ʻoi aku ka maikaʻi, palekana a hilinaʻi hoʻi i ka hopena BMS no nā pahu pahu lead-acid a me Ni-Cd i nā ʻōnaehana mana koʻikoʻi.
E hoʻokaʻaʻike iā DFUN i kēia lā e ʻike pehea e hiki ai i kā mākou hāmeʻa BMS ʻoi loa ke pale aku i kāu ʻenehana ikehu.
